I am reviewing the situation re high hedges and I still am not able to get an answer to hedge height and list loss spreadsheet, amendments - enter height of floor above ground, else enter zero. The property affected is a bungalow - i.e., a ground floor? what does this amendment mean?

Other question relates to if a hedge cannot be seen by rest of the garden surely the whole garden cannot be taken into account. I have asked this before but the answer I received was not clear
